When one of them fails, the other inlet pipes or inlet pipes shall meet the requirements of fire water consumption and water pressure.
When the underground water pump coupler is used, there should be obvious signs.
Garden design is a process of creating a beautiful natural environment and living and recreational environment by means of garden art and engineering technology in a certain region, through transforming the terrain (or further building mountains, folding stones and managing water), planting trees, flowers and plants, building buildings and arranging garden roads.
When there are four vertical pipes, two non adjacent ones can be closed, and the valve shall have obvious opening and closing signs.
The water pump combiner shall be set in an outdoor place convenient for fire engines, and the distance from the outdoor fire hydrant or fire pool should be 15 ~ 40m.
For tower houses with 18 floors and below, no more than 8 households on each floor and a construction area of no more than 650 square meters on each floor, when it is difficult to set up two fire standpipes, one standpipe can be set, but double valve and Double Outlet fire hydrants must be used.
Based on different reinforcement properties such as bearing capacity reinforcement, functional reinforcement and durability reinforcement, the characteristics and engineering application examples of various new reinforcement methods are summarized, and ideal reinforcement methods with different reinforcement properties are put forward.
Because of the extreme cultural concept of modern times, modern people abandon the traditional “Feng Shui” as a relic.
The above ground water pump coupler should be used.
The flow of each water pump combiner shall be calculated as 10 ~ 15 L / s.
We should look at the problem from a dialectical perspective rather than blindly negating it.
Garden design is closely related to culture, which embodies the spiritual connotation of the unity of heaven and man in traditional culture and expresses the meaning of harmonious coexistence between man and nature.
The indoor fire water supply pipeline shall be arranged in a ring.
The construction project supervision unit is entrusted by the owner to control the quality, cost and progress of the construction project, manage the contract and information, coordinate the relationship between the parties involved in the project construction, and perform the legal responsibilities for the safety production management of the construction project during the construction stage in accordance with the laws and regulations, project construction standards, survey and design documents and contracts.
Different maintenance and reinforcement methods are put forward for the damage of engineering structures.
There shall be no less than two inlet pipes of the indoor fire water supply ring pipe network and the inlet pipes of the regional high-pressure or temporary high-pressure water supply system.
Engineering supervision is a kind of paid engineering consulting service; Entrusted by Party A; Supervision is mainly based on laws, regulations, technical standards, relevant contracts and documents; The supervision principles are law-abiding, honest, fair and scientific; The purpose of supervision is to ensure the quality and safety of project construction, improve the level of project construction and give full play to the investment benefits.
The masonry structure adopts the plate wall shotcrete anchor reinforcement method, the concrete beam and column adopt the carbon fiber reinforcement method, the concrete beam and column adopt the steel bonding reinforcement method, and the concrete beam, column and foundation adopt the enlarged section reinforcement method.
When signing the construction project supervision contract, if the construction unit entrusts the survey, design, warranty stage and other relevant services together, the work scope, content, service period, remuneration and other relevant terms of the relevant services shall be specified in the contract.
Construction project supervision contract and other contract documents.
The project supervision unit shall carry out construction project supervision and related service activities in a fair, independent, honest and scientific manner.
In case of difficulty, it shall be ensured that not one standpipe is closed and out of service during pipeline maintenance.
The existing masonry structure and concrete structure in reinforcement design are affected by various factors such as natural environment and service environment, showing defects such as insufficient bearing capacity and excessive variability in varying degrees.
Represented by Suzhou gardens, garden design pays attention to a variety of skills, and the overall concept is always consistent, that is, the harmony between people and the environment.
Although Feng Shui has a lot of dross, it also retains a lot of useful contents.
The implementation of construction project supervision shall comply with the following main bases: 1.
The indoor fire hydrant water supply system and automatic sprinkler system shall be equipped with water pump couplings, which shall meet the following requirements: the number of water pump couplings shall be calculated and determined according to the indoor fire water consumption.
About this idea, Chinese traditional culture has a special knowledge to study, namely “Feng Shui”.
Construction Engineering Survey and design documents; 3.
In addition to the equipment floor without combustibles, indoor fire hydrants shall be set on each floor of high-rise buildings and group houses, and shall comply with the following provisions: fire hydrants shall be set in places that are obviously easy to access, such as near walkways and stairs, and the spacing of fire hydrants shall ensure that there are water guns of two fire hydrants on any part of the same floor to enrich the water column at the same time..
When the fire water supply is vertical partition water supply, the partition within the water supply pressure range of the fire truck shall be provided with water pump combiners respectively.
Laws, regulations and engineering construction standards; 2.
